Am I making the right assumptions - planning

[VJasper86]

I guess I am just wanting some realistic knowledge from people who have been/are going through it.
I am currently looking into what the outcome will be if we decided to separate. Just getting my bearings while I think and make decisions.
D-day is the end of the month by which point we will be having a chat about what we want and how we expect to be able to achieve that.
I am still on the fence but leaning more towards separation. He is in denial that we are even having this discussion.
Anyway I have been on the eligibility checker to see what it implies I could be entitled to. It says with my salary of £26k and my husband at £21k that I could get approx £800 a month UC.
How does child maintenance go if you intend to go 50/50?
Surely we would end up paying each other? And me earning more would mean I'd pay him more than he paid me.
We own a home together with maybe £100-140k equity.
I also have savings that are currently over the threshold so I wouldn't get UC, but the intention would be to try and use the savings and the equity to get a place on my own (if that's even possible as with childcare costs I am not sure anyone would loan me even though it would probably only be 50% ltv) and then I would be entitled to UC I guess??
That should then help with the childcare costs?
It feels scary as cost of living is going up so much and I hate the idea of hurting dh and him not being with his kids, but I don't know if this is the life I want and I am logical, detail driven, make lists and plan so I want to be prepared for whatever the outcome is.
Thanks for any tips or advice.

You refer to a husband so it’s safe to assume you married.

All assets and liabilities need to shared, including your savings, equity, debt and pensions. The split will be determined by needs Your housing need is broadly the same for both of you because of 50:50 shared care.

As you are the higher earner and will have UC income on top you may get a smaller share of the assets. He is likely to need a bigger % because your income enables you to get a bigger mortgage.

A 50/50 shared care means no CMS. It should be your primary goal to ensure the children maintain a solid relationship with both parents.

Thanks @LemonTT

I did think that as I was a slightly higher earner that it could have an impact. I think in general we have a very similar amount savings wise as we have always tried to split funds across our isa's and keep it even as we have always considered it "our" money.

If we do go down the route of separation/divorce I presume that you can make your own financial decisions and agree those outside of what a court would award?
If I had more in savings than him then I'd go along with the required split of assets as at the end of the day I'd want both of us to be financially stable and the kids to feel at home with both of us. However some general research says that most banks wouldn't lend me enough to buy somewhere anyway even on my current salary.

I would be interested how he would play asset division though as most of the savings in my account are from recent gifts from my parents as he always used to be the high earner whilst I took the maternity leave.
I don't know if we will end up in this situation, but I like to feel prepared.

Also crapping my big girl pants as the fact that I am actually looking onto the logistics feels brutul.
